Best Buy is selling the iPhone 6 and 6S for $1 for 3 days

The 16GB 6S normally retails for $200 with a two-year contract, and the 16GB 6 goes for $100 with a two-year contract. In a significant drop from its regular $200 price tag, Best Buy retailers are drumming up a last-minute holiday sale: the iPhone 6s is now on sale for $1 until Sunday.

But a new number generally signals a new flagship feature: the iPhone 4 had the Retina display; the iPhone 5 had a bigger display, LTE, and a Lightning port; the iPhone 6 had an even larger display and Apple Pay. Apple CEO Tim Cook has often maintained an “iron-like grip” on Apple’s product pricing, so it’s surprising for Apple customers to see such a large bargain this holiday season. But for Best Buy, who is struggling to compete with other retailers and online shoppers, it’s a smart tactic to attract more customers into the store. Aftermarket waterproof cases exist for cameras and phones, though they’re bulky and cumbersome—they’re fine if you want to go diving and take some pictures, but not so great to leave on all the time. Several vendors, including Samsung, have developed waterproof phones, which range from water-repellant coatings to fully submersible devices that can withstand a certain amount of time underwater. (Challenges still remain, such as using the touchscreen while submersed.) Apple too has—ahem—dipped its toe into waterproofing.

The Apple Watch is water-resistant and has an “ingress protection” rating of IPX7, which means it can be immersed in up to 1 meter of water for 30 minutes. And now that we’re all carrying our smartphones everywhere, the chances of dropping one in a puddle, a pool, or even the toilet have increased drastically.

The company is currently priced at $51.5 billion, according to its most recent annual sale. “Fiscal 2015 was Apple’s most successful year ever, with revenue growing 28% to nearly $234 billion. This continued success is the result of our commitment to making the best, most innovative products on earth, and it’s a testament to the tremendous execution by our teams,” said Tim Cook, Apple’s CEO. “We are heading into the holidays with our strongest product lineup yet, including iPhone 6s and iPhone 6s Plus, Apple Watch with an expanded lineup of cases and bands, the new iPad Pro and the all-new Apple TV which begins shipping this week.”

It’s also not great for Apple because when you break your phone, through whatever means, and get a new one, Apple can take apart the old phone and either refurbish it, or use parts for repairs. While it’s possible that Apple can reuse at least parts of some water damaged phones, there are probably also a lot of parts that aren’t worth salvaging, depending on the level of damage.

After all, one less port means one less thing Apple has to worry about waterproofing. (I’m not convinced that’s worth the trade-offs, but it certainly might go into the calculus.) The touchscreen remains the single biggest problem for having a phone that actually works with water, and it might not be one that Apple solves right away. For good reason too: There’s no need to encourage people to test out the water-resistance of their phones, nor to incur any false advertising claims when water damage actually does occur. So don’t be surprised when next year’s iPhone ad features droplets of water running over the surface of the phone, or the keynote highlights an Apple executive’s snorkeling trip to Hawaii, complete with underwater photos.
